Hi wondering if anyone can help with fixing my bios. Currently experiencing power on but flashing power led.
I'll attach the old one and the link the model from Lenovo Website and what I got extracted from that exe file. I removed the excess lines and will attach that one too but flashing it didn't seem to work.

Hi all,
I've got a Lenovo ideapad gaming 3 15IMH05 with a black screen issue. I've tried a BIOS file which i saw in another post and changed some things in a Hex editor.
So i transfered the DMI info from my original BIOS to the one i got from the post. Flashed it to the chip and the laptop was booting again but very slow post.
After a couple of boots it went back to black screen again. Tried to flash the same BIN file on it which i used before but its staying at the black screen now unfortunately.
I hope someone can help me out. Attached is my ORIGINAL... -
Has anyone been experiencing issues with Lenovo's USB-C IC (SN2001024YBGR)? I have had three separate laptops with the same part getting over 100 degrees on the thermal scope this week. If you are familiar with this laptop, could you please lend me some help in troubleshooting the charging circuit? I also have been having the same issue with another laptop which is the same chip but its a Lenovo Thinkpad E15 Gen 2....

Hey guys, I have a Lenovo Ideapad 320-15ikb NM-B241 rev:1.0.
After turning it on, it runs for a few seconds then shuts off completely. No screen, no fan. After shutdown, a red light comes on and off fast. I've been trying to troubleshoot this for days now. It's never been opened up; the Lenovo sticker is still intact.
(!)I tried with a different BIOS battery, without any ribbon cables, on battery power, without the keyboard, and it's always the same.
Any insights on what might be causing this?... -
Good day.
I'm trying to figure out what's wrong with a Lenovo Ideapad S130 motherboard. When I connect it to the bench PSU and limit the supply to ~2.2A (about the limit of the lenovo stock PSU), the board absorbs all the amperage and the voltage on the PSU drops down to about 4-5V.
The components on the board that get hot are the two mosfets ( 1 and 2 on the photo ) and the CPU. The resistance to ground measured on the power rail coils can be seen on the image (~17 and ~50 ohms). On the top of the CPU there are few caps which measure dead short. I checked all caps on the top side...
